OIL-REGULATOR FOR CONTINUOUSLY-FED LAMPS.

SPECIFICATION forming part of Letters Patent No. 520,61 1, dated May 29,1894:.

e Appli i filed January 8, 1894. Serial No. 496.090. (No model.)

To all whom it may concern.-

Be it known that I, HERBERT S. PULLMAN, of Meriden, in the county of NewHaven and State of Connecticut, have invented a new ImprovementinOil-Regulators for Continuously-Eed Lamps; and I do hereby declare thefollowing, when taken in connection with accompanying drawing and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawlug constitutes part of thisspecification, and represents, in the figure, a view, partly inelevation and partly in section, of a lamp-fountcontaining my invention.

My invention relates to an improvement in regulators for the founts ofthat class of lamps which are used in conjunction with an apparatusfeeding a continuous supply of oil, the object being to produce a simpleand rehable regulating device of positive and automatlc operation,composed of few parts and not liable to derangement.

With these ends in view, my invention consists in a regulator, havingcertain details of construction and combinations of parts, as will behereinafter described and pointed out in the claims.

{XS herein shown, the lamp-fount consists of a circular body A and ahead'B, which is inserted in and secured to the open upper end of thebody, the same being provided at its lower end with two oppositelyprojecting hollow arms C C, carrying burners, which are not represented.I would have it understood, however, that I do not limit myself toconstructing the fount in any particular way, as any fount of approvedform may be employed 1n carrying out my invention. 'Within the fount Ilocate a large float D, of any suitable material, which is provided uponits upper face with two brackets E E, located opposite each other, andeach having an upright vertically slotted arm. The slots of the saidbrackets receive the outer ends of two correspondin g operating-levers FF, the inner ends of which are pivoted to lugs or hangers G G, dependingfrom the inner face of the head B, before mentioned, on opposite sidesof the center thereof. The said levers are thus flexibly connected, asit were, at their outer ends with the float, which causes them to beraised and lowered as it rises and falls in the fount.

When the float rises, the outer ends of the arms will be pushedfartherthrough the slots in the brackets, as indicated by broken linesvalve J in the form of a pad, at a point directly under the reducedlower discharge-end or nozzle of the feed-pipe K which dischargesvertically downward. When the float is raised by the inflow of oil intothe fount, it will operate through the medium of the levers F F and thelinks H H, to positively raise the valve-bar I, and hence draw the valveJ against the lower end of the feed-pipe and close the same, whereby theinflow of oil into the fount is temporarily stopped. Then, as the oil isconsumed by the burners at the ends of the arms C, the float willproportionately fall and cause the valve to be positively moved awayfrom the discharge end of the feed-pipe, which will again feed oil intothe fount until the raising of the float has lifted the valve intocontact Withit again. As herein shown, the float is centrally cut away,as at D, to clear the valve-pipe I, but that construction is notessential, although it effects an economy of space. The connections ofthe feed-pipeK may be of any suitable charactor, and do not needdescription here, but it will be understood that it is entered into thelower end of a supply-pipe in which it is packed for telescopic or slipmovement, in a manner well known in this art. To provide for thevertical adjustment of the feed-pipe with reference to the valve J, Ifurnish it with a reinforcing sleeve K, which receives the impingementof an adjusting screw L mounted in the hub B extending upward from thecenter of the head B, the said hub receiving the lower end of the shellM, which is provided to inclose the feed and supply pipes. I mightdispense with the reinforcing sleeve K, but I prefer to use the same,inasmuch as the feed-pipe itself is comparatively small and made oflight metal, whereas the sleeve virtually enlarges the size of the pipeand makes it stronger and larger within the range of adjustment and theimpingement of the set screw L. It is apparent that, by raising andlowering the feed-pipe with reference to the valve J, the action of thesame may be closely regulated.

Having set forth the operation of my improved regulator in describingits construction, I need not again refer to its operation more than tosay that the valve is automatically and positively cut into and cut outof operation, which is to say, presented to and withdrawn from thedischarge end of the feedpipe, whereby my device is made perfectlyreliable in its action.

It is apparent that in practicing my invention some changes may be madein the construction and form of the parts shown, and I would thereforehave it understood-that I do not limit myself to such form, but holdmyself at liberty to make such changes as fairly fall within the spiritand scope of my invention. 'I am aware, however, that it is not new toconstruct an automatic oil-regulator with a float, a valve, andconnection between the float and valve whereby the latter is operated bythe rising and falling of the float, and do not-therefore claim suchconstruction broadly.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an automatic oil-regulator for continuously fed lamps, thecombination with a lamp-fount, of a float located therein, a feedpipeentering the fount and arranged to discharge vertically downward at apoint di- 2. In an automatic oil-regulator for contin uously fed lamps,the combination with a lamp-fount, of a float located therein, avertically adjustable feed-pipe extending downward into the fount anddischarging downward at a point directly over the float, a valveconsisting of an elastic pad interposed between the float and thedischage-end of the pipe, and of a horizontally arranged bar in whichthe said pad is mounted, a plurality of operating levers pivotallyconnected at their upper ends with the fount, and connected at theirlower ends with the float, so as to permit the same to rise and fall,and links depending from the said operating-levers and connected attheir lower ends with the said ends of the bar, substantially as setforth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
